How have you concluded your shocks are "fine"? Because your wheels aren't hopping around like old cadillacs? You've defied even Sachs's service expectations there, bud Your shocks are completely blown three times over (at the very least) likely five times over. As you say, shocks/struts don't have an on/off switch, they begin to degrade as the internal sealing doesn't do its job. I would say around 30,000 miles, stock Sachs-Boge struts/shocks are starting to heavily degrade and performance will be compromised.

The information is for those who will use it correctly. If you choose to not use my information, fine. Don't.

Your car

lol at this. How have you concluded your shocks are "heavily degraded" by 30k miles? Have you ever seen a car with actual blown shocks? The car doesn't have to be hopping, but if my shocks were completely blown it would be. I'd be able to push on a fender and have it bounce. By all means though, continue to blow your cash on stuff you don't need, doesn't bother me at all
